Paris Hilton -- Drops $25K for One Pound of Dog

Paris Hilton goes big when she goes small, dropping $25K on 2 dogs.

Paris just nabbed 2 perky Pomeranians and accompanying bling at Betty's Teacup Yorkies in Canada ... then presented one to mommy Kathy Hilton as a 35th Anniversary gift.

How much dog does 25K get you? We're told Paris' 3-months-old pooch weighs in at 6 oz. while Kathy's 6-month-old pom weighs 12 oz.

You may recall ... Paris dropped $13K for another pom in September.

$40K for less than 2 pounds of dog. Jeez.
